[0001]
BACKGROUND OF THE INVENTION
  The present invention relates to a filter mounting device that forms an intermediate product of a filter cigarette by connecting a filter and a cigarette, and forms a filter cigarette by winding a chip paper piece around the intermediate product.
[0002]
[Prior art]
  In this type of filter mounting device, for example, a double filter cigarette intermediate product is formed by linking cigarettes to both ends of a filter plug having a length corresponding to two filters, and a chip paper piece is wound around the intermediate product. Filter cigarette can be formed(For example, Patent Document 1). Specifically, the filter mounting device includes rotating drum rows, and these drum rows form an intermediate product and convey it. The filter mounting device includes a tip paper roll, and a long tip paper is fed from the roll. The chip paper is coated with glue on one side during the feeding process, and is cut into individual chip paper pieces on a rotating coke drum. The chip paper piece sticks to the intermediate product from the glue application surface at a position where the drum row for conveying the intermediate product and the coke drum face each other, and is wound around the outer periphery by rolling of the intermediate product in the rolling passage. For example, the rolling passage is formed between the coke drum and the rolling plate. When the intermediate product is fed into the rolling passage, the intermediate product is transferred from the drum row onto the rolling plate, and between the coke drum. Rolls in the direction of tip paper piece supply. In this way, the filter plug and the two cigarettes are connected by winding the chip paper piece to form a double filter cigarette. Thereafter, the double filter cigarette is cut from its center to become individual filter cigarettes.

[Problems to be solved by the invention]
  In recent years, in order to improve the productivity of filter cigarettes, the conveying speed of intermediate products tends to increase more and more. For this reason, the rotational speed of the drum row that conveys the intermediate product is also increased, and a very large acceleration acts on the cigarette when the intermediate product is transferred between the drums or transferred in the rotation direction of the drum. . At this time, the spilled spills from the cigarette, the fine powder, and the like are disturbed by the rotation of the drum, and an atmosphere such as fine powder is formed around the intermediate product. If fine powder or the like adheres to the outer surface of the filter plug or the paste application surface of the chip paper piece in this atmosphere, the cut is wound inside the chip paper piece together with the intermediate product. When such engraving occurs, the filter cigarette becomes defective and must be eliminated one by one.
[0005]
  For this reason, in the technical field of filter mounting devices, it is necessary to prevent entrainment of fine powder and the like to prevent defective filter cigarettes from being produced.
[0006]
[Means for Solving the Problems]
  The filter mounting apparatus according to the present invention is configured to convey a filter cigarette intermediate product.Set inEquipped with a dust removal means,, Extending from the vicinity of the end of the transport path to the upstream side of the transport path, on the transport pathAt least cover the filter passage areaA hood that opens toward the transport path andTransport routealongHas a suction port that extends and generates suction through this suction port(Claim 1).
[0007]
  According to the filter mounting device described above, the intermediate product isTransported downstream in the transport pathFine powder spilled from cigarette during processButFloating around the intermediate productHowever, when the intermediate product passes through the hood,InletThroughIt is sucked and removed without sticking to the outer surface of the intermediate product. Therefore, the intermediate product is not exposed to an atmosphere such as finely divided powder, and a clean chip paper piece can be wound around the intermediate product. Therefore, the filter mounting apparatus of the present invention does not produce defective filter cigarettes, and can greatly contribute to the improvement of productivity.
[0008]
  The conveyance path described above includes a row of conveyance drums that rotate while holding the intermediate product on the outer periphery, and the suction port is formed in a circular arc shape along the outer periphery of the conveyance drum.(Claim 2). In this case, the transport route isTransportSince it becomes the shape which winds along the outer peripheral surface of a drum, a suction inlet is formed according to the shape of a conveyance path | route. Thus, if the shape of the suction port is adapted to the outer peripheral surface of the drum, a constant suction force can always be generated around the intermediate product on the transport path, and the dispersion of dust removal performance is eliminated.
[0009]
  The tip paper piece supply means includes a coke drum that rotates while sucking the other surface of the tip paper piece and attaches the tip paper piece to the intermediate product at a position facing the transport drum. Further includes a jet outlet for generating an air flow along the outer peripheral surface of the coke drum and forming an air curtain covering the passage area of the chip paper piece before the entrance of the rolling passage.(Claim 3). In this case, the chip paper piece is supplied by the rotation of the coke drum,At the entrance of the rolling passageAffixed to intermediate product. At this time, the glue application surface of the chip paper piece is exposed on the outer surface of the coke drum just before the entrance of the rolling passage, but the adhesion of the fine powder or the like to the glue application surface here is blocked by the air curtain. By combining the suction port and the air curtain in this manner, the dust removal performance is greatly improved, and both the intermediate product and the chip paper piece can be supplied to the rolling passage in a clean state.
[0010]
  It is preferable that the suction port described above extends to the front of the entrance of the rolling passage.(Claim 4). In this case, the fine powder or the like that moves around the intermediate product is sucked in just before the tip paper piece is finally wound to ensure dust removal from the intermediate product. Thus, if the suction port extends just before the entrance of the rolling passage, the intermediate product is kept clean until just before the tip paper piece is wound.
[0011]
  The suction port may be provided with a porous plate.(Claims 5 and 6). In this case, since the suction port sucks fine powder and the like through the small holes of the porous plate, the suction flow velocity is increased around each small hole. By increasing the suction flow velocity as described above, it is possible to appropriately capture and suck minute ticks.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
  FIG. 1 schematically shows a filter cigarette manufacturing machine to which the filter mounting device of one embodiment is applied. The filter cigarette making machine has a drum row 4 composed of a number of conveying drums, and the drum row 4 is an inlet drum located at one end thereof.8To the rolling section 6 extending laterally. A large number of holding grooves (not shown) are formed on the outer peripheral surface of each drum at equal intervals in the circumferential direction, and each drum holds a cigarette, a filter plug, etc. in the holding groove. Rotate in state. Cigarettes, filter plugs, and the like are transferred between adjacent drums, and are sequentially transferred between the drums. Therefore, the drum row 4 forms a transport path for cigarettes and filter plugs, that is, filter cigarette intermediate products.
[0013]
  Entrance drum8For example, a double-length cigarette having a length corresponding to two single cigarettes is supplied from a cigarette hoist or a cigarette reservoir (not shown). The double-length cigarette is cut into two single cigarettes by the rotary knife 10 in the middle of the drum row 4, and then these single cigarettes are separated from each other in the axial direction.
[0014]
  A plug feeder 12 is disposed above the drum row 4. The plug feeder 12 has a pair of left and right rod hoppers 14, and a number of filter rods are stored in the rod hoppers 14. The filter rod has a length corresponding to 2 to 3 filter plugs, and is supplied to a plug supply machine 12 through a wind pipe from a filter supply device (not shown). A drum row 16 also extends from the outlets of the left and right rod hoppers 14, and this drum row 16 is connected to an assembly drum 18 in the middle of the drum row 4. The drum row 16 takes out the filter rods one by one from the left and right rod hoppers 14 and conveys them toward the assembly drum 18. In this conveying process, the filter rod is cut into two or three filter plugs, and after being subjected to grading, alignment processing, etc., is sequentially supplied to the assembly drum 18 as individual filter plugs. On the other hand, in the assembly drum 18, two single cigarettes are arranged at intervals in the axial direction, and the filter plug is positioned therebetween.
[0015]
  Thereafter, the two single cigarettes are shifted to the center on the next drum, thereby forming an intermediate product of double filter cigarettes in which the single cigarettes are in close contact with both ends of the filter plug. Then, the intermediate product passes through the exit drum 20 located at the leftmost end of the drum row 4 and then the rolling section.6To be supplied.
  The filter cigarette manufacturing machine includes the rolls 22 and 24 of the chip paper P, and the supply path of the chip paper P extends from the rolls 22 and 24 to the rolling section 6. The rolls 22 and 24 are disposed at the upper left end of the main frame 2, and one of the rolls 22 is in use and the other roll 24 is in a standby state. The chip paper P fed out from the roll 22 is guided to a rolling section 6 by being guided by a number of guide rollers on the supply path. In the middle of the supply path, the tip used to replace the roll used from the upstream sidePaperA connecting device 26, a reservoir box 28, a glue applying device 30 for applying glue on one side of the chip paper P, and the like are sequentially arranged.
[0016]
  The chip paper P supplied to the rolling section 6 is cut at predetermined lengths to form chip paper pieces, and these chip paper pieces are attached to intermediate products of the double filter cigarette supplied from the drum row 4 and sequentially wound. It is done. At this time, each chip paper piece is wound around a part extending from the intermediate filter plug to the ends of the single cigarettes on both sides, and the single cigarettes are wrapped and bonded together so that the single cigarettes are attached to both ends of the filter plug. The connected double filter cigarette is formed.
[0017]
  The formed double filter cigarette is supplied to the drum row 32 extending from the rolling section 6 and is continuously conveyed by the drum row 32. In this conveyance process, the double filter cigarette is cut from its center by a rotary knife to form two filter cigarettes, and then the two filter cigarettes are separated and conveyed in the axial direction. The filter cigarettes are individually subjected to quality inspections such as tipping and air permeability, and as a result, defective filter cigarettes are excluded from the drum row 32. A conveyor 34 is connected to the end of the drum row 32. The conveyor 34 receives the filter cigarettes from the drum row 32, aligns them in one direction, and conveys them to a packaging machine (not shown).
[0018]
  FIG. 2 shows an enlarged view of the rolling section 6 described above. The rolling section 6 includes a coke drum 36, and the chip paper P is supplied from the outer peripheral surface of the coke drum 36. The coke drum 36 is disposed above the outlet drum 20 and the inlet drum 38 so as to connect between the outlet drum 20 of the drum row 4 and the inlet drum 38 of the drum row 32.
[0019]
  The outer peripheral surface of the coke drum 36 is slightly wider than the overall length of the intermediate product I of the double filter cigarette, and the central portion is a suction surface over the entire periphery when viewed in the width direction. Therefore, the chip paper P guided through the supply path is adsorbed to the suction surface of the coke drum 36 with the paste application surface facing outward. The coke drum 36 rotates in the opposite direction to the outlet drum 20 and supplies the chip paper P along with the rotation.
[0020]
  A bladed drum 40 is disposed adjacent to the upper right of the coke drum 36, and the bladed drum 40 rotates in the opposite direction to the coke drum 36. Knives 42 project from the outer periphery of the bladed drum 40 at equal intervals in the circumferential direction. The bladed drum 40 cooperates with the coke drum 36 on its outer peripheral surface as the blade rotates. The chip paper P is cut into chip paper pieces for each predetermined length.
[0021]
  A rolling plate 44 is disposed below the coke drum 36, and the upper surface of the rolling plate 44 has an arc shape along the outer peripheral surface of the coke drum 36. A rolling passage curved downward is formed between the rolling plate 44 and the coke drum 36, and the height of the rolling passage is set slightly smaller than the diameter of the intermediate product I.
[0022]
  When the intermediate product I is fed into the entrance of the rolling passage, the intermediate product I rides on the rolling plate 44 and starts rolling. At this time, with the rotation of the coke drum 36, chip paper pieces (not shown in the drawing) adsorbed on the outer peripheral surface enter the rolling passage in synchronization with the rolling of the intermediate product I, and apply the glue. Affix to the outer periphery of the intermediate product I from the top of the surface. The intermediate product I with the chip paper piece attached is rolled by friction with the rolling plate 44 in the rolling passage, and the chip paper piece is wound around the outer periphery of the intermediate product I with this rolling. At this time, since the coke drum 36 releases the suction force to the chip paper piece in the rolling passage, the chip paper piece can be smoothly peeled off from the outer peripheral surface of the coke drum 36 when being wound around the intermediate product I. it can. The intermediate product I, for example, rotates about 3 times in the rolling passage, and during this time, the intermediate product I comes out of the rolling passage while ensuring adhesion with the chip paper piece. When the winding of the chip paper piece is completed, the double filter cigarette DF is formed as described above.
[0023]
  The above is the specific content of the process of winding the chip paper piece around the intermediate product I. At this time, in the vicinity of the outlet drum 20, for example, fine powder spilled out from the cigarette is disturbed and flies around the intermediate product I, and the fine powder or the like of the fine product adheres to the intermediate product I or the coke drum. If it adheres to the chip paper piece on 36, the cut will be wound inside the chip paper piece. Further, the fine powder that floats may jump between the intermediate product I and the chip paper piece during the winding process of the chip paper piece, and may be caught as it is.
[0024]
  More specifically, when the outlet drum 20 receives the intermediate product I from the drum 46 on the upstream side, the outlet drum 20 conveys the intermediate product I upward at a high speed in the rotational direction while pulling upward from the receiving position. At this time, as indicated by the arrows in the figure, the fine powder or the like is swung up in the conveying direction of the intermediate product I and is scattered around the intermediate product I. Among the scattered fine powder and the like, a heavy one may immediately fall and adhere to the outer surface of the intermediate product I, and a light one may float and reach the coke drum 36. In addition, fine powder may be spilled from the end of the cigarette being conveyed through the drum row 4 and may float around the intermediate product I. For this reason, the filter mounting apparatus according to the present embodiment includes equipment for removing dust and the like in the vicinity of the rolling section 6.
[0025]
  FIG. 3 specifically shows the above-described dust removal equipment, in which two suction chambers 48 and 50 of the dust removal equipment are shown in cross section. One suction chamber 48 is located between the outlet drum 20 and the drum 46 on the upstream side thereof, and opens to face the outer peripheral surfaces of the drums 20 and 46, respectively. The other suction chamber 50 is located above the outlet drum 20 and opens downward facing the outer peripheral surface of the outlet drum 20. The openings of the suction chambers 48 and 50 are adjacent to each other and are continuous in the rotation direction of the outlet drum 20, that is, the conveyance path direction of the intermediate product I.
[0026]
  FIG. 4 shows only one of the suction chambers 48 described above, and the suction chamber 48 will be described in detail below with reference to FIGS. 3 and 4.
  The suction chamber 48 has a hood plate 52 that defines its ceiling, and the hood plate 52 is formed in a cross-sectional groove shape as shown in FIG. A pair of side walls 54 and 56 are attached to both sides of the hood plate 52 in the rotation direction of the drum row, and the suction chamber 48 is formed between the side walls 54 and 56. Further, the side walls 54 and 56 extend downward from the hood plate 52 so as to enter the gap (valley) between the outlet drum 20 and the drum 46. Therefore, the lower ends of the side walls 54 and 56 are matched to the shape of the gap. It is formed in a sharp shape. And the lower edge of these side walls 54 and 56 is extended from the lower end so that it may open in a V shape, and is formed in circular arc shape along the outer peripheral surface of the exit drum 20 and the drum 46. Accordingly, when the opening of the suction chamber 48 is viewed relative to each of the outlet drum 20 and the drum 46, the opening is formed in a circular arc shape along the outer peripheral surface of the outlet drum 20 and the drum 46. .
[0027]
  A nozzle 58 is attached to the above-described hood plate 52 so as to protrude obliquely upward, and this nozzle 58 communicates with the suction chamber 48. A suction hose 60 is connected to the nozzle 58, and a suction pressure is supplied into the suction chamber 48 from a suction source (not shown). Thereby, the opening of the suction chamber 48 becomes a suction port facing the outer peripheral surfaces of the outlet drum 20 and the drum 46, and a suction force can be generated through this suction port.
[0028]
  Further, as shown in FIG. 4, a punching metal 62 is attached to the opening of the suction chamber 48, that is, the suction port, and the punching metal 62 is bent according to the curvature of the opening. For the punching metal 62, for example, a product with round holes of 60 ° staggered is used.
  FIG. 5 shows the other suction chamber 50. Next, the suction chamber 50 will be described with reference to FIG. 3 and FIG.
[0029]
  The suction chamber 50 also has a hood plate 64 which extends above the outlet drum 20 along its outer peripheral surface. A pair of side walls 66 and 68 are provided on both sides of the hood plate 64 in the rotational direction of the outlet drum 20, and the suction chamber 50 is formed between the side walls 66 and 68. Further, the lower edges of the side walls 66 and 68 are formed in an arc shape along the outer peripheral surface of the outlet drum 20. Therefore, the opening of the suction chamber 50 is also formed in an arc shape in cross section along the outer peripheral surface of the outlet drum 20. It has been made.
[0030]
  Above the outlet drum 20, a suction pipe 70 extending in the axial direction of the outlet drum 20 is disposed at a position before the entrance of the rolling passage described above, and the hood plate 64 is connected to the peripheral wall of the suction pipe 70. . Food plate 64ofThe side walls 66 and 68 are similarly connected to the side wall of the suction pipe 70, and the peripheral wall of the suction pipe 70 is cut out in the suction chamber 50. One end of the suction pipe 70 is closed by the end plate 72, and the other end is bent in the direction opposite to the rotation direction of the outlet drum 20. A suction hose 60 is connected to the bent end, and the suction pressure is similarly supplied to the suction chamber 50. Therefore, the opening of the suction chamber 50 serves as a suction port facing the outer peripheral surface of the outlet drum 20, and a suction force can be generated through this suction port. Similarly, a punching metal 62 is attached to the suction port of the suction chamber 50.
[0031]
  A bracket 74 is provided above the suction pipe 70, and this bracket 74 extends in the axial direction of the suction pipe 70. The suction pipe 70 is connected to one end of a bracket 74 via an end plate 72 that closes one end thereof, and the suction pipe 70 is further connected to the bracket 74 via a lug 76 on the front side of the machine body. The bracket 74 is fixed to the airframe constituent member 78 on its upper surface.
[0032]
  FIG. 5 shows an air blow nozzle 80 as another dust removing equipment. The air blow nozzle 80 is of a so-called fishtail type, and a large number of jet nozzles (not shown) are formed in a straight line at the tip thereof. The air blow nozzle 80 is connected to a blow pipe 82, and blow air is supplied to the blow pipe 82 from an air pressure source (not shown). The other end of the bracket 74 described above protrudes toward the front side of the machine body, and a holder block 84 is attached to the front end portion thereof. The blow pipe 82 is held by being clamped to the holder block 84, and is fixed to the airframe constituent member 78 through the bracket 74 together with the air blow nozzle 80.
[0033]
  Each outlet of the air blow nozzle 80 is directed to the inner side of the machine body, and these outlets form a line. The rows of jet nozzles are arranged in a direction along the outer peripheral surface of the coke drum 36 as shown by a two-dot chain line in FIG. Accordingly, blown air is simultaneously ejected from the respective outlets of the air blow nozzle 80, thereby generating an air flow toward the inner side of the machine body along the outer peripheral surface of the coke drum 36. This air flow flows in a direction intersecting with the supply direction of the tip paper P, and forms an air curtain that covers the passage region of the tip paper piece just before the entrance of the rolling passage described above. The effective range of the air curtain formed by the air flow is shown in FIG. 3 by a region A surrounded by a one-dot chain line. However, since the area A is slightly separated from the passing area of the intermediate product I being actually transported, the air curtain does not disturb the transport of the intermediate product I.
[0034]
  As shown in FIG. 4, the width W of the suction port is wider than the filter plug portion FP of the intermediate product I. Further, the suction port of the suction chamber 50 has the same width W, and the width W of these suction ports is wider than the width of the chip paper P as shown in FIG. The two suction ports of the suction chambers 48 and 50 are continuous in the rotation direction of the outlet drum 20 and cover the passage region of the filter plug portion FP from above the outlet drum 20. Further, these two suction ports extend along the outer peripheral surface of the outlet drum 20 in the conveying direction of the intermediate product I, and the end thereof reaches the entrance of the rolling passage (see FIG. 3).
[0035]
  As described above, when the intermediate product I of the double filter cigarette is conveyed by the outlet drum 20, the fine powder or the like that has been disturbed around the periphery is sucked through the suction ports of the suction chambers 48 and 50 and collected through the suction hose 60. Is done. The suction hose 60 is connected to a dust collector (not shown), and the sucked fine powder and the like are appropriately processed by the dust collector. At this time, the suction port covers the passage area of the filter plug portion FP, and the width W thereof is sufficiently wider than the width of the chip paper P. Therefore, the intermediate product I is particularly fine in the vicinity of the winding area of the chip paper piece. Isolated from the atmosphere.
[0036]
  Further, since the suction port extends just before the entrance of the rolling passage, the intermediate product I is isolated from the atmosphere such as fine powder all the way to the position just before the transfer from the exit drum 20 to the rolling plate 44. For this reason, it is possible to send the intermediate product I into the rolling passage in a clean state, thereby effectively preventing the generation of defective products. Even if fine powder or the like adheres to the filter plug portion FP, the fine powder or the like is sucked immediately before the entrance of the rolling passage and is finally removed from the intermediate product I.
[0037]
  On the other hand, when the chip paper piece is supplied by the coke drum 36, the fine powder or the like flying toward the paste application surface is blocked by the above-described air curtain. For this reason, fine powder or the like does not adhere to the paste application surface of the chip paper piece, and the chip paper piece can be supplied to the intermediate product I in a clean state.
  Further, since the punching metal 62 is attached to each suction port, the suction flow velocity is increased around each small hole. For this reason, even if it is a minute time, it can be reliably sucked in the suction chambers 48 and 50, and its dust removal performance is enhanced.
[0038]
  The present invention is not limited to the above-described embodiment, and can be implemented with various modifications.
  In the filter cigarette manufacturing machine shown in FIG. 1, a rolling path of the intermediate product I is formed between the coke drum 36 and the rolling plate 44. However, a rolling path is separately provided between the rolling drum and the rolling hand. It may be formed. Specifically, a coke drum is disposed in the vicinity of the drum upstream of the rolling drum, and chip paper pieces are supplied to the intermediate product of the double filter cigarette on the drum upstream of the rolling drum. Then, the intermediate product supplied with the chip paper piece rolls while being guided by the rolling hand on the outer peripheral surface of the rolling drum. Therefore, the suction chamber is disposed in the vicinity of the drum on the upstream side of the rolling drum, and the air curtain is formed in the vicinity of the position where the upstream drum and the coke drum face each other.
[0039]
  In the above-described embodiment, the case where the intermediate product I is supplied to the rolling plate 44 through the upper half side of the outlet drum 20 is described, but the conveyance path of the intermediate product I is formed on the lower half side of the outlet drum 20. May be.
  In the above-described embodiment, the suction chambers 48 and 50 are separated, but the suction chambers 48 and 50 may be integrally formed. Further, the suction port of the suction chamber may be disposed not only in the vicinity of the outlet drum 20 but also in the vicinity of the drum 46 on the upstream side or other drums in the drum row 4.
[0040]
  In addition, the suction chambers 48 and 50 of the above-described embodiment are arranged on the outer periphery of the outlet drum 20 or the like, that is, outside the passage region of the intermediate product I with respect to the outlet drum 20 or the like. You may arrange | position inside the passage area of I. Specifically, a plurality of support portions for sucking and holding the intermediate product I are formed on the outer periphery of the outlet drum 20 at intervals in the axial direction, and these support portions are formed from the outer peripheral surface of the outlet drum 20. Protrusively formed. Each intermediate product I is sucked and held in a holding groove formed in the support portion, and is conveyed along with the rotation of the outlet drum 20. At this time, a groove is formed in the circumferential direction of the outlet drum 20 between the adjacent support portions, and therefore a gap is secured between the outer peripheral surface of the outlet drum 20 and the intermediate product I being conveyed. Yes. Therefore, by arranging the suction chamber in the gap, fine powder and the like can be sucked into the outlet drum 20 inside the region where the intermediate product I passes. In this case, the suction surface of the suction chamber has an arc shape in cross section toward the outside of the outlet drum 20.
[0041]
  Further, the specific specification of the punching metal 62 is not limited to the 60 ° staggered round holes, but the pitch, hole shape, arrangement, etc. may be changed as appropriate. Further, the direction of air flow forming the air curtain, the length and width of the air curtain, and the like can be appropriately changed according to the position, size, shape, and the like of the coke drum.
  In addition, a suction hole is opened at the bottom of the holding groove described above, and a suction passage is formed in the support portion through each suction hole. The suction passage communicates with the suction chamber inside the outlet drum 20 or the like, and each intermediate product I is in a state of being sucked through the suction hole. The opening area of the suction hole is usually set to be the same as the cross-sectional area of the suction passage. However, if the opening area of the suction hole is increased at the bottom of the holding groove, the suction hole is sandwiched between the holding groove and the intermediate product I. It is also possible to suck in time. In this case, it is possible to remove the time that cannot be sucked by the suction chambers 48, 50 and the like.
[0042]
  In addition, it goes without saying that the specific shapes and specifications of the various members constituting the suction chambers 48 and 50 and the air blow nozzle 80 can be appropriately changed.
[0043]
【The invention's effect】
  The dust removing means of the filter mounting device according to claims 1 to 6 removes dust from the intermediate product immediately before the intermediate product with the chip paper enters the rolling path from the conveyance path. Fine powder or the like will not adhere, and as a result, defective filter cigarettes will not be produced, greatly contributing to the improvement of productivity.
